PATENT throne CHARLES A. WATKINS, OF GREEK STREET, SOHO SQUARE, ENGLAND.

BRUSH-MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,576, datedSeptember 21, 1880. Application filed December 18, 1879. Patented inEngland June 19, 1879.

To all whom it may concern Be it known that I, CHARLES ADOLPHUS WATKINS,of the firm of Hamilton 85 00., brush manufacturers, of Greek street,Soho Square, in the county of Middlesex, England, have made certain newand useful Improvements in Brush-Machines, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, and to the letters of reference marked thereon. p

Figure l is a side elevation, Fig. 2 a front elevation, and Fig. 3 avertical section, through the revolving axis of my improved machine.Fig. 4 is a plan view of the brush-handle upon which it is desired tobind the bristles by use of my improved apparatus.

Like letters of reference wherever they occur indicate correspondingparts in all the figures.

The object of my invention is primarily to produce a simple, cheap, andconvenient apparatus for binding the bristles upon a new and peculiarconstruction of brush,which forms the subject of a separate applicationfor Letters Patent filed herewith; but the improvements are alikeapplicable for winding other forms of brushes. I

The invention involves certain new and useful combinations orarrangements of parts and peculiarities of construction, all of whichwill be hereinafter first fully described and then pointed out in theclaim.

A is the bed-plate, and A A the standards supporting the hollowrevolving mandrel B.

O is a crank or handle fixed at one end of the mandrel and serving as amedium through which said mandrel may be revolved at the pleasure of theoperator. Thiscrank may obviously be replaced by a pulley of anyordinary form, and the usual appliances for arresting or reversing themotion may be adopted, such as the shifting-belt or the well-known formsof clutches.

Upon the opposite end of the mandrel is the face-plate or disk D,centrally perforated to correspond with the cavity in the mandrel, andcarrying the lugs or projections 61 d, cast thereon or otherwise affixedthereto. The rim of disk D is rabbeted, as at E, forming a seat for thetoothed band F, made like the rim of a crown-wheel and G G are handlesattached to the band F for convenience in turning it upon its seat.

The vise for holding the brush consists of two jaws or plates, P P,overlapping each other, and so shaped that when placed in the positionshown in the drawings they leave an open ing, 0, concentric with theopening or cavity in the mandrel and conforming to the size and shape ofthe brush to be wound. The plates P P are attached to the blocks H H,which slide in suitable grooves formed in the projecting pieces orblocks d d, and are moved by the screws 8 8 working in them. Thesescrews 8 8 turn in fixed bearings at II, and are keyed to the pinions SS, which gear into the toothed ring or band F. By turning the band F inonedirection-say to the lef tby means of the handles G G, the plates P Pare caused to slide away from each other and increase the size of theopening 0. When thisis sufficientlylarge the brush-handle is insertedinto the hole in the mandrel at K, the block B, Fig. 4, resting on itsend, which is adjusted to allow the peg A to project about one-half aninch beyond the plates P P. The bristles are then inserted in theopening O, around the pegA. The handles G G are then moved back, slidingthe toothed rightwhich, by revolving the pinions S S and correspondingscrews, forces the jaws P P together until the bristles are firmly heldbetween them, when the binding-wire, which has been attached to the pinN, is wound on the brush by turning the handle 0, and is finally securedby tying or soldering, or by any known method. String or cord may beused for the binding instead of wire.

In the winding of the bristles, or binding them upon the particular formof handle shown in Fig. 4, after which they are to be protected by asocket or ring, it is important that the plates P P be made thin inorder to occupy but little space upon the bristles, and it is alsoimportant that these plates be sufficiently removed from the face-plateof the machine to accommodate the block B in the rear of them, whichblock is secured to the handle of which the pin Ais but an extension.

By making the plates thin and overlapping band F in the oppositedirection-say to the each other the opening Khas a continuous orunbroken wall,with0ut which the bristles could notbe properly locatedupon the peg A.

The machine constructed and arranged in accordance with the foregoingdescription is simple, convenient, and efficient for the purposesintended, and by its use the bristles may be more firmly bound than bythe usual hand processes, and the winding accomplished in a more uniformand rapid manner.

Instead of the base shown in the drawings, it is proposed, also, to useone which will at the same time accommodate a screw-press for thepurpose of adjusting the ferrules upon the brushes after being wound,thus making the two machines in one; but the screw-press is not'hereinillustrated, and forms no essential part of the presentinvention. It is,however,

made the subject of a separate application for Letters Patent.

- 'I am fully aware of the existence of many forms of screw-clampsaffording an extended bearing upon the material or object to be held inplace, and not applicable to the uses and purposes of my improvedmachine. To these old forms I desire it understood that I make no claim;but,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a machine for making brushes, the combination of two or more slidingplates or jaws adapted to hold the brush when being tied and a rotatingmandrel, the jaws being made of thin metal and forming the completewalls of the brushopening, all operating substantially in the manner setforth.

I In testimony that I claim the foregoing I have hereunto set my handand afliXed my seal in the presence of two witnesses.
